T0 at whom, it may concern:

Be it known that 1, JAMES MILLER SMITH, residing at Wengler, in the county of Shasta and State of California, have invented certain new and useful Improvements in Miter- Boxes and Saw-Guides, of which the following is a specification.

My invention relates to certain new and.

My invention has for its object to provide a miter-box and saw-guide of the foregoing character of a very simple and effective construction which can be easily and cheaply manufactured, which will readily serve its intended purposes, and which is capable of use with any kind of saw, either stifl -back or common saw or meat-saw.

vVith other objects in view than have been heretofore enumerated the invention also comprises certain novel construction, combi-.

nation, and arrangement of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which 1 Figure 1 is a perspective view of my invention. Fig. 2 is a plan view thereof. 7 is a front elevation of the miter-box shown in Fig. 1. Fig. 4 is a vertical section taken on the line 4 4 of Fig. 2. Fig. 5 is a perspective view of the inside saw-engaging member.

Fig. 6 is a cross-section on the line 6 6 of Fig. 7. Fig. 7 is a perspective view of the outside sawengaging member. Fig. 8 is a cross-section on the line 8 8 of Fig. 5. Fig. 9 is a perspective view of the sawengagingmember connecting-bar. Fig. 10 is a detail perspective view of the saw-guide complete detached from the box.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the figures, 1. designates the base, which is substantially triangular in shape for a purpose presently explained. Bolted or otherwise secured to the base 1 at its rear edge 1 is a Fig. 3

block 2, forming'a straight edge against which the timber or board to be cut is placed and to which the supporting-frame 3 of the saw guide mechanism is secured. The frame 3 is formed of strap-iron 3, having a longitudinal slot 3 running throughout its length and having its ends 3 3 bent up at right angles to the base portion 3 to form standards, as shown. The standards 3 3 are slotted, as at 3, for a purpose presently understood.

The frame3 is adjustably secured to the block 2 by the bolts 2 2, which pass through the base 1, the block 2, and the slot 3 in the base portion 3 of the frame 3 and are secured by thumb-nuts 2 2 In practice the base 1 of the miter-box preferably has its rear edge 1 about eighteen inches long, while the block 2 is about fourteen inches long by one and onehalf inches high and one and one-half inches wide. The strap-iron 3 has its base portion 3 about fifteen inches in length in practice, and its end standards 3 3 are about four and one-half inches in height, the slot 3 in the base 3 being about threeeighths of an inch wide. The slot 3 in the outer standard 3 is preferably of less width than that of the inner standards 3 for a purpose now to be explained.

4 designates a rod forming a part of the saw holder and guide, which projects through the slot 3 of the standards 3 3 and is secured to the standards by nuts 4 4 on the threaded portions 4 4, respectively, of the rod, the diameter of the threaded portion 4 being greater than that of the portion 4 to avoid.

the necessity of threading the rod throughout its length, the portion 4 cooperating with the standard 3 while the portion 4 cooperates with the standard 3, as shown. The rod 4 at the inner. end 4 next the saw S is square in crosssection and provided with a vertical slot 4 and a horizontal slot 4, for a purpose presently understood.

5 and 6 designate the saw-engaging members or guides proper which comprise the sheet-metal plates 5 6, whose upper and lower edges are bent over to form flanges 5 6 to form the plates into a dovetail shape in cross-section to receive the dovetail portions 7 8 of the blocks 7 and 8 of hard wood or other suitable material, each of which blocks 7 8 have their upper edges extended upwardly, as at 7 8 to form bearing portions for the rod of a stiff-back saw to ride on when such a saw is used. The plate 6' has a pair of cars 6 6, stamped up out of the same in parallel vertical planes spaced about six inches apart in practice, to which ears the horizontallydisposed semicircular scaled arcuate support 9 is pivotally secured by bolts 9 9, as shown. The scaled arcuate support 9 passes through the slot 4 of the rod 4 and is secured by a thumb-screw 4 as shown, to permit adjustment of the saw-guides at different angles to the vertical. Midway the ends of the plate 6 and at right angles to the ears 6 6 the plate 6 has asecond pair of cars 6 6 stamped therefrom, which ears 6 6 lie in parallel horizontal planes in practice about three inches apart, A second semicircular scaled arcuate support is pivotally secured to the ears 6 6 by bolts 10 10 as shown, to permit adjustment of the saw-guides at different angles to the horizontal. The scaled arcuate support 10 passes through the slot 4 of the rod 4 and is secured by a thumb-screw 4 as shown.

11 designates a yoke member having parallelly-arranged arms 11 11 one of which terminates in bifurcated portions 11 11 and said parallel arms are bolted or riveted to plates 5 6", as shown, The screw member 11 serves to hold the plates 5 6 in. proper correlative position. The yoke member 11 is preferably formed of spring-steel, and the sawengaging members 5 and 6 are held the desired distance together by the adjustable bolt 12, which passes through the arms 11 11 and is secured by the thumb-nuts 12, as

shown.

In the drawings I have shown my inven tion as adapted for use as a right-handed miter-box, and by simply removing the i rame 3 from the base 1 and turning it through an angle of one hundred and eighty degrees and again securing it to the base 1 the apparatus becomes a left-handed miter-box.

In practice the braces 9 and 10 will be provided with suitable calibrations a and as shown, to enable the saw to be directly set in the position desired by simply observing the reading of the calibrations on the braces 9 and 10.

My invention can also be used to saw wood of a greater size than will fit in. the boxes by simply setting the box on the wood and clamping the frame 3 in a position drawn toward the end of the boxes until the'saw is cleared of the base edge, when the desired cut can be readily made.

The apparatus can be used to cut a miter or bevel either with the work in the boxes or under the same. In framing heavy timbers the boxes can be set on the timber and worked in that manner. The rod 4 when slightly loosened will readily turn to allow the guides 5 and 6 to adapt themselves to the movement connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my invention will be readily understood by those skilled in the art to which it appertains, and I desire to say that many slight changes in the de tailed construction and arrangement of parts can be m adc without departing from the spirit of the invention or the scope of the appended claims.
